iSync lets you manage your contacts, calendars, To Do lists, and Safari bookmarks across multiple Mac OS X computers and devices (such as an iSync-compatible mobile phone, Palm OS device, or iPod), so you always have your most current information with you. To sync a Palm OS device, you need to install the iSync Palm Conduit version 1.2 or later.
iSync 1.4 includes support for more Symbian OS smart phones and the iPod mini, as well as stability improvements.
Before you install iSync 1.4, you must install iCal 1.5.1 or later. To download the latest version of iCal, visit [url=http://www.apple.com/ical]http://www.apple.com/ical[/url]
If you are using Mac OS X version 10.3 and plan to synchronize a Bluetooth mobile phone, you need to have Bluetooth version 1.5 or later installed. To download it, use Software Update (in System Preferences). If you have an earlier version of Mac OS X, visit [url=http://www.apple.com/isync]http://www.apple.com/isync[/url] to download the appropriate Bluetooth version.
iSync now has calendar, contact, and to-do synchronization for the Nokia 6600, 3620, 3660 and Siemens SX1. With these phones iSync also syncs the Address Book picture to the contact info, so you can see a picture of the caller when the phone rings. In addition, Mac users in Japan can now sync over 110 Japanese mobile phones when they purchase a third-party USB cable.
iSync 1.4 is available via Software Update or can be downloaded from Apple’s website. More info and download link here.
